本篇文章為大家展示了使用Django怎么調(diào)用支付寶接口，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。
支付寶支付
正式環(huán)境:用營(yíng)業(yè)執(zhí)照,申請(qǐng)商戶(hù)號(hào),appid
測(cè)試環(huán)境:沙箱環(huán)境:https://openhome.alipay.com/platform/appDaily.htm?tab=info
支付寶提供接口:給商戶(hù)使用,收錢(qián)
-Java,php,C#的demo,沒(méi)有python的demo
-git有人封裝了
-需要安裝模塊:pip3 install
-應(yīng)用私鑰---自己保存,一定不能丟
-應(yīng)用公鑰---給別人用
-支付寶公鑰---支付寶用的
-生成公鑰私鑰:https://docs.open.alipay.com/291/105971
-把應(yīng)用公鑰配置在支付寶上:應(yīng)用公鑰,配置完成以后,支付寶自動(dòng)生成一個(gè)支付寶公鑰
-在程序中:配置應(yīng)用私鑰,支付寶公鑰
-如果支付成功,支付寶會(huì)回調(diào),但是如果你的服務(wù)器掛掉了怎么辦?
-支付寶24小時(shí)以?xún)?nèi)不定時(shí)再給你發(fā),你修改掉訂單狀態(tài)即可
-支付成功,支付寶會(huì)有一個(gè)get回調(diào),一個(gè)post回調(diào):修改訂單狀態(tài)
